GENERAL INFORMATION
The Model 1431/1432 auto-dial modem is used to allow communication between any of the
EUROPLEX 3000 series control panels and an off-site computer using the PANELMAN soft-
ware or a central/monitoring station equipped with the Model 1430 auto-answer modem/
EUROPLEX 4000 series polling multiplexer interface. The auto-dial modem is usually installed
inside the EUROPLEX 3000 series subscriber’s control panel and is connected to the serial
communications port of the panel which provides 12 volts DC power and the serial data to
operate the modem. An 8-conductor modular cord connects the modem to the telephone
company CA-38A jack.
INSTALLATION
The Model 1431/1432 auto-dial modem comes with an 8-
conductor modular cord and mounting hardware. This
hardware must be used to satisfy ULC requirements. Slide
the nylon bushing onto the threaded stud on the back of the
control panel. Note the clearance hole in the modem beside
the telephone jacks. Remove the protective backing from
the foam tape on the modem and then position the modem
clearance hole over the stud and press the lower end of the
modem onto the steel box. Place the flat washer on the stud
and use the hex nut to secure the top of the modem.
WIRING

or serial communications port of the control panel printed circuit board as shown in the chart on
page 69.
